The TUBA 1" 1/4 float level switch is a small diametertubularfloat that has been designed to fit tanks and cisterns having restriced access. Its small 1" 1/4 diameter allows it to pass through the narrow openings usually found on the side walls of tanks. As the liquid level reaches the float, the mechanical switch inside will tilt, thus closing or opening a circuit connected to an electrical panel. Thanks to its +/-20º switching angle, the TUBA float level switch ensures a very precise level measurement..
